Abstract

The relative intensities of resonantly scattered gamma rays by 48Ti, at room and liquid-nitrogen temperatures, were measured in TiC, TiO2, and TiH2 with use of the nuclear-resonance photon-scattering technique. The results enable determination of the effective temperature Te and the Debye temperature D of Ti in the various compounds with assumption of the Debye model. A significant increase in Te and θD of the Ti atoms was observed in TiC and TiO2, while no detectable change in Te and θD was observed in pure Ti upon hydrogenation. The present results are discussed and compared with data obtained by other techniques.
